This, the 40th stamp in the Black Heritage series, honors Dorothy Height (1912–2010), the tireless activist who dedicated her life to fighting for racial and gender equality. Although she rarely gained the recognition granted her male contemporaries, she became one of the most influential civil rights leaders of the 20th century.

After college at New York University, Dorothy Height worked as a teacher in the Brownsville Community Center, Brooklyn, New York. She was active in the United Christian Youth Movement after its founding in 1935.

In 1938, Dorothy Height was one of ten young people selected to help Eleanor Roosevelt plan a World Youth Conference. Through Eleanor Roosevelt, she met Mary McLeod Bethune and became involved in the National Council of Negro Women.

Dorothy Height became national president of Delta Sigma Theta in 1947, after serving for three years as vice president.

In 1957, Dorothy Height's term as president of Delta Sigma Theta expired, and she was selected as the president of the National Congress of Neighborhood Women, an organization of organizations. Always as a volunteer, she led NCNW through the civil rights years and into self-help assistance programs in the 1970s and 1980s.

She built up the organization's credibility and fund-raising capacity such that it was able to attract large grants and therefore undertake major projects. She also helped establish a national headquarters building for NCNW.

She was also able to influence the YWCA to be involved in civil rights beginning in the 1960s, and worked within the YWCA to desegregate all levels of the organization.

Height was one of the few women to participate at the highest levels of the civil rights movement, with such others as A. Philip Randolph, Martin Luther King, jr., and Whitney Young. At the 1963 March on Washington, she was on the platform when Dr. King delivered his "I Have a Dream" speech.

Dorothy Height traveled extensively in her various positions, including to India, where she taught for several months, to Haiti, to England. She served on many commissions and boards connected with women's and civil rights.

"We are not a problem people; we are a people with problems. We have historic strengths; we have survived because of family." - Dorothy Height
